Adobe Sign sort users by "Member Of" and "Last Login"

Since the update of the All Users-interface I cannot sort our users in the columns "Member Of" and "Last Login" anymore. As all new colleagues need to get their Adobe Sign-settings and group membership adjusted, I cannot find them easily any more. Please bring this feature back.

If I check from "Groups" and then look for the members of the "Default group", I cannot change the "User Group" when checking the settings of one user. Please adjust this interface.
